  1. FAAAAACK! Gotta sooper sleuth the Gee Dee passive values. Seriously, it doesn't cost a thing to have them in the schematic.
  2. I'm putting this together now. BOM is horrible. What values are ALL the resistors? P.S. Why, why why SMT? PITA, no?
  3. "@swampdonkeykami Thank you for the review!" You may be mistaking me for somebody with an obscure youtube channel.
  4. Got an interesting problem with my second kit. Turn on. No display. randomly mash buttons. displays 0000000 for split second, then blank. Check power and pin voltages... 1- 3V 2-7 1.3V 8-13 0.3V 14-15 1.3V 16 3V 17-18 0V 19 0.3V 20 0V I assume I did something wrong like insert LEDs wrong way. Start cutting leads off (hate de-soldering) Bingo. LEDs light up missing a couple segments. LED installed correctly. Faulty/fried bubble module?
  5. All good! Wrong tongue angle. Love the programmable easter egg! Well done.
  6. Got my two. Chips no flashed? I must have mis-read that they were flashed... Is there an Energia sketch, or am I forever destined to be the dumb kid eating paste in the corner?
  7. i'll buy 2 kits. bluehash---------------1---------US cubeberg---------------2---------US GeekDoc----------------2---------US Greeeg-----------------1---------AUS Swampdonkeykami----2---------CA
  8. I'm in for a deluxe version. Let me know where to send da moneys.
  9. *thinking* or we could install a pressure transducer and have the 43oh calculate the volume of air @ X pressure and base all movements on that baseline pressure, then don't need any fancy geometry algorithms for axies! THANKS FOR THE INSPIRATION GUYS!!!!!
  10. Glad you like! More fun in the works! No, this came out of a gold mining machine. I'm re-purposing for something completely useless. ;-) As for varying loads, yes and no. If you are talking lifts various weight of items, shouldn't make a difference because the cylinder volume is constant. You put in 3 litres of compressed air @ 30psi, the cylinder moves 500mm. You put in 3 litres of compressed air @ 200psi, the cylinder moves 500mm. The trick is, the 43oh needs to return to a known position (full retract, full extend, or limit switch) prior to changing the load. But if the load v
  11. Now that we know it works, I'm bustin' out more cylinders and joystick controls! :thumbup:
  12. Hi Guys! I've been toying with an idea, that I didn't think would work, and set up a test jig. Using an air compressor, a solenoid valve, a flow meter and a 43oh I found that we can get a repeatable cylinder position, like +-2.5 mm! The flow meter is measuring the volume of air that we've fed to the cylinder and the 43oh opens or closes a solenoid valve depending on the cylinder position.http://arduinoforgoodnotevil.blogspot.ca/2013/10/accurate-ish-pneumatic-cylinder.html
  13. "Select the appropriate chip. (NOTE all the libraries work with the MPS2553, if you have the older launch pad 1.4 serial and string libraries won
  14. Long story short: sometimes it works and sometimes it don't. I've read through every post related to the 43oh serial monitor in Energia. I've tried it on three different computers running XP and Windows 7. I'll get it to work, close the window, upload the sketch again and then the serial monitor won't work. MSP-EXP430G2 Rev 1.4; 2553 chip with RX TX jumpers kriss-crossed. Any body else have same trouble? any suggestions?
  15. Even more impressive! Thanks for showing us what great projects can be accomplished even without all the tools. Too often people put up false barriers; "I could do that, if only I had a 3D printer. If only I had a CNC mill. If only I could program..." :thumbup: Well done sir!
  16. Man! You must have a lot more patience than I do! When you build V. 2 :thumbup: ; I'll send you some copper coated steel rod. It's filler rod for tig welding, but the copper coating will make it easy to solder/braze.
  17. 2131 2001 2013 Sometimes, I can get a program to upload even if it's not on the "tools/board:" list by using 2231 (1MHz). Just getting lucky? Nothing to do with UART? Will TI's Code Composer get around this?
  18. Wah?! That's great, you did a great job getting the wire straightened!
  19. Is there a n00b friendly way to upload sketches to MSP430Gs that don't have built in UART? (How do I use all these free samples? :!!!: )
  20. Is the structure solid copper or copper plated steel (TIG filler rod)?
  21. Jaw dropingly good! You'll be able to get much better torque/power with your new system!
  22. One of them fancy new fangled magnetostrictive pulse gewgaws? Pricey, no?
